It contains, as active substance, a 2-chloro-4-trifluoromethyl-thiazole-5-carboxylic acid derivative of the formula I <IMAGE> in which R represents an organic radical which has not more than 40 carbon atoms and which can, if appropriate, also contain nitrogen, oxygen or sulphur, and which can be converted by hydrolysis and/or oxidation into a carboyl group which is bonded to the thiazole ring. These compounds are distinguished by a good microbicidal action and are used for controlling or preventing infection of plants with phytopathogenic microorganisms. Some of these compounds are known, many are new. The novel 2-chloro-4-trifluoromethyl-thiazole-5-carboxylic acid derivatives and their preparation are also a subject of this invention. |
